In this example I am trying to fill the ellipse with the default strokeColor. I tried to replace `color="default"` with `strokeColor`, `invert` but it doesn't quite work.
<shape h="100" w="100" aspect="variable" strokewidth="inherit">
<background>
<rect x="0" y="0" w="100" h="100" />
</background>
<foreground>
<stroke />
<fillcolor color="default" />
<ellipse x="0" y="0" w="100" h="100" />
<fillstroke />
</foreground>
</shape>
How can I define a filled ellipse that will have the same color as stroke?
